# DateTime.Millisecond プロパティ

## 定義

このインスタンスで表される日付のミリ秒の部分を取得します。Gets the milliseconds component of the date represented by this instance.

``````public:
property int Millisecond { int get(); };``````
``public int Millisecond { get; }``
``member this.Millisecond : int``
``Public ReadOnly Property Millisecond As Integer``

#### プロパティ値

DateTime のミリ秒部分 (0 ～ 999)。The milliseconds component, expressed as a value between 0 and 999.

## 例

``````System::DateTime moment = System::DateTime(
1999, 1, 13, 3, 57, 32, 11 );

// Year gets 1999.
int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

// Day gets 13.
int day = moment.Day;

// Hour gets 3.
int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;

``````
``````System.DateTime moment = new System.DateTime(
1999, 1, 13, 3, 57, 32, 11);
// Year gets 1999.
int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

// Day gets 13.
int day = moment.Day;

// Hour gets 3.
int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;
``````
``````Dim moment As New System.DateTime(1999, 1, 13, 3, 57, 32, 11)

' Year gets 1999.
Dim year As Integer = moment.Year

' Month gets 1 (January).
Dim month As Integer = moment.Month

' Day gets 13.
Dim day As Integer = moment.Day

' Hour gets 3.
Dim hour As Integer = moment.Hour

' Minute gets 57.
Dim minute As Integer = moment.Minute

' Second gets 32.
Dim second As Integer = moment.Second

' Millisecond gets 11.
Dim millisecond As Integer = moment.Millisecond
``````

## 注釈

"Fff" 書式指定子を使用して、Millisecond プロパティの文字列形式を表示できます。You can display the string representation of the Millisecond property by using the "fff" format specifier. たとえば、次のコードでは、コンソールへの日時のミリ秒数を含む文字列が表示されます。For example, the following code displays a string that contains the number of milliseconds in a date and time to the console.

``````DateTime date1 = new DateTime(2008, 1, 1, 0, 30, 45, 125);
Console.WriteLine("Milliseconds: {0:fff}",
date1);           // displays Milliseconds: 125
``````
``````Dim date1 As Date = New Date(2008, 1, 1, 0, 30, 45, 125)
Console.WriteLine("Milliseconds: {0:fff}", _
date1)       ' displays Milliseconds: 125
``````

また、"o" 標準書式指定子を使用して、日付と時刻の値の他のコンポーネントと共にミリ秒部分を表示することもできます。You can also display the millisecond component together with the other components of a date and time value by using the "o" standard format specifier. 次に例を示します。For example:

``````DateTime date2 = new DateTime(2008, 1, 1, 0, 30, 45, 125);
Console.WriteLine("Date: {0:o}",
date2);
// Displays the following output to the console:
//      Date: 2008-01-01T00:30:45.1250000
``````
``````Dim date2 As New Date(2008, 1, 1, 0, 30, 45, 125)
Console.WriteLine("Date: {0:o}", date2)
' Displays the following output to the console:
'      Date: 2008-01-01T00:30:45.1250000
``````

ただし、"o" 書式指定子は、ラウンドトリップまたは @no__t 0 値の格納に対しては表示されません。However, the "o" format specifier is intended less for displaying than for round-tripping or storing a DateTime value. 次の例に示すように、カスタム書式指定文字列を使用して、ミリ秒を他の日付/時刻コンポーネントと共に表示することもできます。You can also display milliseconds together with other date and time components by using a custom format string, as the following example shows.

``````DateTime date3 = new DateTime(2008, 1, 1, 0, 30, 45, 125);
Console.WriteLine("Date with milliseconds: {0:MM/dd/yyy HH:mm:ss.fff}",
date3);
// Displays the following output to the console:
//       Date with milliseconds: 01/01/2008 00:30:45.125
``````
``````Dim date3 As New Date(2008, 1, 1, 0, 30, 45, 125)
Console.WriteLine("Date with milliseconds: {0:MM/dd/yyy HH:mm:ss.fff}", _
date3)
' Displays the following output to the console:
'       Date with milliseconds: 01/01/2008 00:30:45.125
``````
